One object of the invention is to provide an improved lighting fixturecomposed of only two sections which'have interlocking parts so that whenthe sections are assembled only one screw rivet or similar fastener willbe necessary to provide a sturdy assembly.

'Another object is to provide on the rear or base-section of the fixturea projectionor projections adapted to not only hold one side of thesocket and globe carrying section but also to coact with the bead orgroove on the neck of the globe and thus help in holding the globe sothat only one globe screw will be needed.

Another object is to provide a fixture of this character which willeffect savings both in materials and in assembly time, since the twosections may be molded of phenolic resin or similar insulating plasticmaterial, are quickly and easily assembled and are securely fastenedtogether by the use of a single fastening screw. 1

With the above and other objectsv and advantages-in view, the inventionresides in the novel combinations and arrangements of parts and thenovel features of construction hereinafter described and claimed, andillustrated in the accompanyingdrawings which show the present preferredembodiment of the invention.

FIG. 3 is a bottom view of the main or base section of the fixture;

FIG. 4' is a rear view of the base section;

FIG. 5 is a top view of the lamp and globe carrying section;

FIGS. 6 and 7 are detail sectional views taken on the lines 6-6 and 77respectively in FIG. 2, on an enlarged scale. I

Referring more in detail to the drawings, the numerals 1i}? and 11denote the two sections of the fixture, each of which is preferablymolded in one piece from a moldable plastic insulating material such asphenolic resin. The

main or base section Iii is of generally right angular but as shownthere is a centrally positioned screw 14 threaded into a hole at thecenter of a slotted cross bar 15.

The arm 13 is formed with a passageway 16 for electric conductors but asshown it is hollow with its inner end opening through the plate 12 andits outer end 17 is closed. Viewed from the :top the arm 13 is outwardlytapered and it comprises forwardly converging upright side walls 18 withreduced outer portions, a short flat bottom wall 19 connecting the innerportions of the side walls, the end wall 17 and a top wall 20 which mayhe stepped or ribbed as shown to make the bracket more attractive inappearance. The passageway or chamber 16 in the arm 13 also opensthrough the bottom face of the arm and that opening is closed by theother section 11 of the fixture.

The preferably removable section 11 is adapted to carry an electric lamp23, shown in dotted lines, and a surrounding light diffusing globe orshade 24 which may be of any desired shape buthas the usual reducedannular neck with a peripheral groove or bead 25. The section 11comprises a pan-shaped body with a preferably flat and circular top wall26 surrounded by a circular depending side wall or rim 27 of a size toreceive the neck of the globe, as shown in FIG. 1. The bottom edges ofthe side walls 18 are cut away from the front end wall 17 to a pointadjacent the short bottom wall 19 to receive the major portion of thesection 11; and the upper surface of the top wall 26 of that sectionabuts those bottom edges while, as shown, a portion of the circular rim27 abuts the arcuate front edge 29 of the bottom wall 19 of the bracket,as will be seen upon reference to FIGS. 1 and 2.

In order that a single screw, rivet or similar fastener 30 at the outerportion of the hollow arm 13 may be usedto hold the sections'ltl and 11assembled, an interengaging connection between the two sections isprovided at their inner or rear portions. That connection may takevarious (forms but comprises one or more projections on the bottom wall19 to at least underlie some portion of the rim 27. As shown there aretwo upstanding ribs 31 formed on the top of the wall 19 in laterallyspaced relation and extending in a forward and rearward direction,

the outer projecting ends 32 of the ribs extending through spacednotches 33. formed in the lower edge of the rim or wall 27'. Theprojection or projections 32 are disposed at the side of the section 11opposite the location of the screw 30 which passes upwardly through ahole 34 formed in the top wall 26 and is engaged in an internally screwthreaded hole 35 formed in the bottom of the thickened outer end 17 ofthe arm 13 of the bracket. To strengthen the hole 35 the inner or rearside of the end wall 17 is formed with an upright enlargement or rib, asseen in FIG. 4. The threaded hole 35 is preferably molded in accordancewith the disclosure in the Baxter et al. Patent 2,775,916, January 1,1957. To further strengthen theconnection of the two sections 10 and 11,the screw 30 extends through an upwardly projecting circular boss 36formed on the top of the wall 26 and adapted to seat in a similarlyshaped socket 37 in the bottom of the end wall 17 concentric with thethreaded hole 35. In assembling the two sections the pan-like section 11is tilted to engage the tongues or projections 32 in the notches 33 andthe outer portion of that section is then swung upwardly against thebottom edges of the side Walls 18 so that the boss 36 enters the socket37. A

' screw, rivet or similar fastening may then be inserted and shape whenviewed from the side and comprises a prefertightened to hold thesections interlocked and provide a sturdy assembly.

As previously noted, projections 32 also coact with one or more screwsin holding the globe 24 on the section 11, a single screw 40 beingpreferably used. To accorn plish that additional function theprojections 32 are made sufficiently long to extend into the groove inthe neck of the globe and engage under the head 25, as shown in FIG. 1.The screw 40 is threaded in a hole formed in the rim 27 at a pointsubstantially diametrically opposite the projection or projections 32,and its end projects under the bead 25. By thus using the projections itis only necessary to provide one screw 40 to hold the globe and onefastener 30 to hold the fixture assembled. I

Molded at the center of the top wall 26 of the section 11 is the body 41of an electric light socket to receive the screw threaded plug of thelamp 23. This socket is a cylindrical upright shell molded integrallywith the wall 26 and has a top 42 which projects slightly above the' topof that wall. The lamp socket is of the usual con-, struction as seen inFIGS. 6 and 7. It comprises the usual internally threaded metal shell 43and the metal center contact plate 44. Positioned in the top wall 42 arethree metal eyelets 45, 46 land 47. The eyelet 45 fastens the centercontact 44 and in its top may be soldered one of the electricalconductors. The contact 44 is a generally rectangular strip of metal setin a channel in a thickened portion of the wall 42. The other twoeyelets 46 and 47 extend through the spaced top portions of the metalshell 43 to fasten it. In one of the eyelets 46, 47 may be soldered theother electrical conductor. These conductors 48 extend through thechamber or passageway 16 in the arm 13. The plastic insulating bodyportion 41 of the socketmay be reenforced or strengthened by uprightribs 49 molded on its outer surface below the wall 26.

From the foregoing, taken in connection with the laccompanying drawing,it will be seen that novel and advantageous provision has been made forcarrying out the objects of the invention, and while preferences havebeen disclosed, attention is invited to the possibility of makingvariations within the scope of the invention as claimed;
